Discussion on the paper "Optimal Magnetic Momentum Control for Inertially Pointing Spacecraft"

Publication Date
  • Computer Science
  • Mathematics


The paper by Maro Lovera proposes a novel momentum unloading algorithm for an inertially stabilized spacecraft. The spacecraft is actuated by reaction wheels working in zero momentum bias. The periodic control theory is used for synthesis of a controller compensating external disturbances by means of reaction wheels and magnetic actuators. The key issue is an observation that the magnetic field as observed from a low earth orbit is almost periodic
